the infected don't smell blood

Rating: 9/10 (7 July 2005)

the scene where Hannah is hiding behind the mirror and the infected comes in, he is like 20cm from her head and cant find her...because he cant see her! my point is that don't the zombies smell humans or sth like that? i think that in dawn of the dead they could smell humans...but here it is not like that..any comments?
another thing...the infected were supposed to be starved to death..so said thesoldier but they don't actually eat the humans..they just spread the infection..and Jim does not say that he killed a zombie or has not considered that little boy to be one..so these things give me a thought that this movie could be a metaphor for this world..people killing people...survival... any comments? otherwise this movie is great..kept me on the screen all time!
